This is a preliminary design for dual-axis tracking for solar panels.

This is a work in progress, and has not yet undergone physical testing. If you choose to use it, use at your own risk, and please share your feedback in the comments.

The idea is that the sensors are small PV cells. They are indicated as batteries for the simulation to work. They would be aimed in the indicated direction, so the sensors in the direction of the sun would receive more light than the other. It simulates properly for both single and dual axis use.

If you only want single axis, you can eliminate the bottom half, or build the board and simply not attach the North/South sensors and motor.

There is more design work to do, to allow for automatic parking. Where I am can have very heavy winds sometimes. During normal years, we have recorded up to 119mph sustained winds, but the majority of the wind is 17mph or less. I will probably add an anemometer sensor (dc motor attached to a cup type rotor), but that physical design is beyond the scope of the electronics schematic.
